3 Claims.

This invention appertains to new and useful improvements in ineans for collecting and trapping foreign particles in the lubricant of engine lubricating systems.

The principal object of this invention is to provide a novel trap for installation in the crank case of an automobile, whereby sediment will be trapped and not permitted to circulate in the lubricating system.

During the course of the following specification, other objects of the invention will become apparent to the reader.

In the drawings:-

Figure 1 represents a side elevational view of l5 an engine partly broken away to disclose the novel trap installed therein.

Fig. 2 represents a rear end elevational view of the engine showing the closure plate.

Fig. 3 represents a sectional view taken substantially on line 3-3 of Fig. l.

Fig. 4 represents a perspective view of the tray section of the trap.

Fig. 5 represents a perspective view of the cover section of the trap.

it can be seen in Fig. 4, that the tray section of the trap consists of a rectangular shaped tray 5 having side walls and end walls and a handle 6 at one end. The bottom of this tray is provided with a multiplicity of parallel corrugations '7.

The cover section of the trap is denoted by numeral 8 and is provided with depending side and end walls for slip engagement over the side and end walls of the tray 5.

The top of this cover 8 is provided with a plu- 85 rality of parallel struck-out portions 9 to define depending inclined baffle tongues 10. It can now be seen, that as the heavier particles of sediment fall upon the cover 8, they will slide down the deiiectors 10 and come to rest upon the tray 5 and between the corrugations 7 thereon.

Obviously, during the operation of the engine, the force of the pump 11 will be immediately over the portion 12 of the cover 8 which is not struck out. It will also be observed that the direction of disposition of the baille 10 on one side of the undisturbed portion 12 are in converged relation to the baiiie tongue 10 on the opposite side of the portion 12 and it will also be observed that the tongues 10 are substantially at right angles to imaginary lines drawn from the pump 11, so that the suction of the pump is from the undisturbed portion 12 and from the baille or deflector tongues 10 and not directly through the openings in the cover 8.

One end of the crank case is provided with an Serial No. 628,404

openng over which the closure plate 13 is disposed and suitable securing means 14 may be provided for securing this cover plate snugly over the opening so that no oil can leak through,

While the foregoing speciiication sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. @d

Havng thus described my invention, what I claim as new iszl. A trap of the character described for crank cases comprising a tray, a cover for the tray, said cover being provided with slots therein, and tongue members extending from the edges of the cover at the slots downwardly toward the tray.

2. A trap of the character described for crank [n cases comprising a tray, a cover for the tray, 5 said cover being provided with slots therein, tongue members extending from the edges of the cover at the slots downwardly toward the tray, said tray being provided with corrugations on the bottom thereof.

3. A trap of the character described for crank cases comprising a tray, a coverfor the tray, said cover being provided with slots therein, tongue members extending from the edges of the cover at the slots downwardly toward the tray, said cover being provided with an unslotted portion intermediate the ends thereof, and between a pair of slotted areas, the tongues of one area being disposed in converging relation with respect to the tongues of the other area.
